Facilitators and Barriers to Implementation of Perineal Techniques: A Scoping Review Applying the Consolidated Framework for Implementation Research

AIM

To summarise the barriers and facilitators to the clinical implementation of perineal techniques and to provide evidence-based insights for decision-making based on existing research.

DESIGN

A scoping review.

DATA SOURCES

Nine electronic databases (PubMed, Cochrane Library, Embase, CINAHL, ProQuest, CNKI, WanFang, VIP and SinoMed) were systematically searched on 4 February 2024.

REVIEW METHODS

This study followed Joanna Briggs Institute's scoping review methodology. The barriers and facilitators identified in the included studies were mapped to the domains of the Consolidated Framework for Implementation Research (CFIR): intervention characteristics, outer setting, inner setting, characteristics of individuals and process.

RESULTS

A total of 18 studies were finally included and analysed. The most frequently identified facilitator was theoretical education for midwives (inner setting). Common barriers included: lack of time to implement perineal techniques (intervention characteristics); labour pain and women's stress due to insufficient understanding of the birthing process, as well as women's reluctance to receive the perineal techniques (outer setting); risk factors for OASIS (inner setting); insufficient theoretical education for midwives and inadequate prenatal education for pregnant women (inner setting) and concerns about potential medical disputes among performers (characteristics of individuals).

CONCLUSIONS

Many of the factors influencing the implementation of perineal techniques identified in this review are modifiable. Developing implementation strategies based on these factors can promote the successful implementation of these perineal techniques in clinical settings.

IMPLICATIONS FOR THE PROFESSION

This scoping review could serve as a reference framework for health authorities in developing strategies to promote the use of perineal techniques in clinical practice.

IMPACT

Existing research has primarily focused on the outer setting, inner setting and characteristics of individuals implementing perineal techniques. Therefore, there is a need for more high-quality studies focusing on intervention characteristics and the implementation process.

REPORTING METHOD

This study followed the PRISMA extension for scoping reviews.

Effects of different techniques during the second stage of labour on reducing perineal laceration: An overview of systematic reviews

AIM AND OBJECTIVE

To summarize the evidence on the effects of different techniques during the second stage of labour on reducing perineal laceration depending on available systematic reviews to provide optimal evidence for decision-making.

BACKGROUND

Preventing perineal laceration has been considered an important part of improving women's health. Various techniques have been used to prevent perineal laceration during the second stage of labour. However, systematic reviews evaluating the effects of different techniques on reducing perineal laceration show inconsistent results.

DESIGN

Overview of systematic reviews.

METHODS

Five English and four Chinese databases were systematically searched for relevant systematic reviews and meta-analyses published between 1 January 2016 and 31 August 2021. The quality of the included reviews was assessed by the AMSTAR 2 tool. A narrative synthesis was conducted to report the results of moderate-to-high quality systematic reviews. The overview was reported according to the PRISMA statement.

RESULTS

Eighteen reviews were included, of which four reviews had moderate-to-high methodological quality. Perineal massage and warm compresses significantly decreased the incidence of third- or fourth-degree perineal laceration (moderate-quality evidence). Hands-off technique had no impact on perineal laceration (low-to-moderate quality evidence). Ritgen's manoeuvre could reduce the incidence of first-degree perineal laceration but increase the incidence of second-degree perineal laceration (very low-quality evidence). Spontaneous pushing (low-quality evidence) and delayed pushing (moderate-quality evidence) had no impact on the incidence of third- or fourth-degree perineal laceration. Upright positions did not increase the risk of third- or fourth-degree perineal laceration (very low- to low-quality evidence) but increased the risk of second-degree perineal laceration for women without epidural analgesia (low-quality evidence).

CONCLUSIONS

Perineal massage and warm compresses could be the better choice for preventing perineal laceration in the second stage of labour.

RELEVANCE TO CLINICAL PRACTICE

Midwives and obstetricians could use perineal massage and warm compresses to prevent perineal laceration and should consider women's preferences and experience with perineal techniques.

Incidences of Atonic Postpartum Hemorrhage and Related Risk Factors at a Tertiary Hospital in Saudi Arabia

Background: In 2017, there were 295,000 maternal deaths worldwide from preventable causes related to birth. The leading cause of maternal mortality is obstetric hemorrhage. In Saudi Arabia, a paucity of evidence about incidences of atonic Postpartum Hemorrhage (PPH) and related risk factors exists. Therefore, aims were to (a) identify incidences of atonic PPH from 2015 to 2018 (b) determine risk factors of atonic PPH in vaginal birth. Methods: Retrospective chart review with purposive sampling conducted revealed 386 charts, 220 (57%) vaginal birth and 166 (43%) caesarian section (CS). Logistic regression analysis was used. Results: Incidences of atonic PPH were 2.5% from 2015 to 2017, with the rate increasing by 12% from 2017 to 2018. In vaginal birth, significant associations between the severity of blood loss with epidural (F = 6.314, df = 1, p = 0.013), episiotomy (F = 4.38, df = 1, p = 0.038), induction of labor (IOL) (F = 1.224, df = 1, p = 0.004), and Interaction between IOL, AUG, and epidural (F = 7.24, df = 1, p = 0.041) found. Discussion: Increasing rate of atonic PPH confirmed. Epidural, episiotomy, induction of labor, and induction with augmentation are factors associated with severe atonic PPH in vaginal birth.
